Contract Design Services
From transformers and coils to power supply design and production support.
In addition to new and replacement designs for transformers and coils, we support the design of power supply units and analog circuit units. Building on power supply and analog circuit expertise developed over more than 35 years, we provide consistent support from design through production preparation, mass-production support and failure analysis.
Key features
Replacement design of high-frequency transformers
We handle replacement designs for existing high-frequency transformers and coils, as well as new designs, covering design calculations and component selection.
Switching power supply design
We design switching power supply circuits from 20kHz to 200kHz.
Analog circuit design
We support the circuit design of power supply units and analog electronic equipment units.
Electrical circuit failure analysis
We analyze failures in power supply equipment and driver circuits, as well as in transformers and coils, and help prevent recurrence.
Production jigs and inspection equipment
We design and build production jigs and inspection equipment such as turns checkers and automatic withstand voltage testers.
Mass production and production support
After you have completed component layout, assembly and evaluation, we support process design and production preparation for mass production of the unit.
Examples of production jigs and inspection equipment
